The study of buoyant convection for diffusion flames in wildland fires is critical to understanding heating and cooling dynamics related to particle ignition. Studies based on solid biomass fuels are made difficult by short flame residence time associated with fine fuels. An alternative is to use artificial fuel gas rather than relying on pyrolysis of solid fuels to...

The Starkey Project, a large-scale, multidisciplinary research venture, began in 1987 in the Starkey Experimental Forest and Range in northeast Oregon. Researchers are studying effects of forest management on interactions and habitat use of mule deer (Odocoileus hemionus hemionus), elk (Cervus elaphus nelsoni), and cattle. A...

Fourteen authors, ranging from transportation specialists to ecologists, have collaborated to write this very useful compendium describing the newly minted discipline of "road ecology." The authors state that road ecology "uses the science of ecology and landscape ecology to explore, understand, and address the interactions of roads and vehicles with...

Three herbicide spraying systems were designed, constructed, and field tested in cooperation with the-USDA Forest Service,.Georgia Forestry Commission, and Scott Paper Company. One system was designed to mount on wildland tree planting machines for applying banded treatments for herbaceous weed control. This system consisted of a top mounted 50-gal tank and a small...

Population growth is rapid in rural areas in California. This growth into the wildland-urban interface makes fire protection and suppression more difficult. Fire managers have opportunities to reduce fire danger by improving housing development patterns; however, the overall density and placement of houses is usually set by criteria other than fire danger. By...

We used simulation modeling to analyze wildfire exposure to social and ecological values on a 0.6 million ha national forest in central Oregon, USA. We simulated 50,000 wildfires that replicated recent fire events in the area and generated detailed maps of burn probability (BP) and fire intensity distributions. We also recorded the ignition locations and size of each...
